Humidity‐driven shape morphing enhances fog harvesting in porous cactus spines
New Phytologist, EarlyView.Spine straightening and water collection during fog exposure in Turbinicarpus alonsoi. Summary Cacti develop spines instead of conventional leaves, which often serve as mechanical defence against herbivores. However, some cactus species grow porous and flexible spines, suggesting fundamentally different functions.

Chinese Journal of Mechanical Engineering, 2020 In gear transmission, temperature rise has a non-negligible impact on the accuracy, noise and transmission efficiency. However, there is no relevant research on the temperature rise of the anti-backlash single-roller enveloping hourglass worm (ASEHW ...

Advances in Wearable Thermoelectric Devices: Strategies for Enhancing Wearability and Performance
Small Science, Volume 6, Issue 9, September 2026.This review introduces wearable thermoelectric devices as body‐integrated systems rather than isolated energy devices. It explains how their performance depends not only on thermoelectric materials but also on skin contact, mechanical compliance, electrical interfaces, and heat‐flow design.

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.Abstract The intensification of disturbance regimes due to climate change is a growing concern in boreal forests, yet the long‐term consequences for forest recovery remain poorly understood, as boreal successional dynamics unfold over a century or longer and exceed the length of available observational records.
